A Reverse Hard-Core Model in ${\mathbb{A}}_2$: an Application of the Pirogov-Sinai Theory

A. Mazel, I. Stuhl, Y. Suhov

In this paper we use the Pirogov--Sinai theory to analyze a class of particle models of Statistical Mechanics on the unit triangular lattice ${\mathbb{A}}_2$. The models are specifie…
